whats the diff between Ex and Lx??

At least for the 4cyl, both are available with cloth interior, EX has sunroof, rear disc brakes, little bit better sound insulation, anti theft on the radio, 6-disc in-dash CD changer (iirc), alloys, dual-tip exhaust. I believe all EX's now come with side-impact airbags, they are an option on the LX.

Special Edition is an LX with a sunroof and some alloys, it may have anti-theft stereo and/or in-dash 6-disc CD changer, but I'm not sure.

The V6's are a little different with the differences.

Biggest reason IMO to buy an EX is the rear disc brakes.
